Return the value of the item including all CONT and CONC lines. This is probably what you want most of the time, and is the function called by default from other functions that return values. If, for some reason, you want to process CONT and CONC items yourself, you will need to use the value() function and probably the items() function.

Return a list of all the sub-items, reading them from the Gedcom file if they have not already been read.

In general it should not be necessary to use this function. The sub-items will usually be accessed by name. This function is only necessary if the ordering of the different items is important. This is very rare, but is needed for example, when processing CONT and CONC items.
